[ltp] [Thinkpad X31] Fan speed = 0

[Maxime DANIS]

Hello Everybody.

I have the feeling that the fan(s) of my thinkpad X31 is/are never used?

# /proc/acpi/ibm/fan

status:       enabled
speed:        0
level:        auto
commands:     level <level> (<level> is 0-7, auto, disengaged)
commands:     enable, disable
commands:     watchdog <timeout> (<timeout> is 0 (off), 1-120 (seconds))
commands:     speed <speed> (<speed> is 0-65535)

I am reading this article

http://www.thinkwiki.org/wiki/How_to_control_fan_speed

But...

 * I prefer to decrease the fan activity threshold than command it manually.
 * I still do not understand if it is a matter of BIOS or Kernel or both?
 * In case 2, Is it related to CPU governors?

thx
